This was a minor earthquake. Quakes this small are rarely felt and do not cause damage.

At this magnitude and depth it was probably too small to be felt, even directly above it. Estimated from magnitude, depth and distance with the intensity equation USGS Did You Feel It? uses; felt reports, where there are any, are the measurement.

How big was it?

This earthquake released about 0.61 lb of TNT. Magnitude is logarithmic: each whole step up releases about 32 times more energy, so a magnitude 1.9 would have released about 32 times as much.

  1. Mineral, Virginia 2011 M 5.8 25,000,000× the energy of this one
  2. Magna, Utah 2020 M 5.7 18,000,000× the energy of this one
  3. Around the size people start to feel M 3.0 1,600× the energy of this one
  4. This earthquake M 0.9 about 0.61 lb of TNT

Energy from the Gutenberg–Richter relation (log10E = 1.5M + 4.8), rounded to two figures; bar length is magnitude, which is already a logarithm of energy. Magnitudes of past earthquakes from the USGS catalogue.

For this area

No earthquake of M4 or more has been recorded within 50 km since our catalogue begins in 2016.

Before 2016, the USGS record lists 4 earthquakes of M5 or more within 50 km:

  1. 6.7 1 km ENE of Dash Point, Washington · 42 km WSW of this epicentre
  2. 5.4 8 km NNE of Lake Marcel-Stillwater, Washington · 38 km N of this epicentre
  3. 5.2 9 km NE of Lake Marcel-Stillwater, Washington · 37 km N of this epicentre
  4. 5.0 3 km WSW of Des Moines, Washington · 37 km W of this epicentre

Since 2016: the QuakeIndex catalogue (US, M1.5+), built from the USGS FDSN event service. Before 2016: USGS ComCat, M5+ from 1900. Distances are between epicentres. This is the record, not a forecast.
